To all whom it may concern:

Be it known that I, ROBERT G.CLARK, of `the borough Vof Brooklyn, county of Kings, and State of New York, have invented a new and useful Improvement in Line-Casting Machines, of which the following is a specification.

This invention relates to that class of. matrix distributing or sorting mechanisms shown in Letters Patent of the United States N o. 347,629. The matrices with which these mechanisms are intended to deal are pro vided at the upper end with a series of suspending and distributing teeth, the matrices for a given character having a number or arrangement of teeth differing from those of matrices containing any other character. The distributer con ists of a horizontal bar provided with long? adinal teeth so grouped or arranged that ei h matrix carried along the bar is sustained oy the interlocking teeth until it arrives at the pointwhere it is to be discharged, when for the first time the teeth bear such relations that the matrix is released. The matrices are commonly carried along the bar by adjacent arallel screws which engage their vertical e ges.

In practice it is frequently desirable, for one reason or another-for example when a matrix is reversed on the bar, or when it stands with one edge in adx ance of the other--to speedily remove t-he'matrices from tliebar.

Heretofore it has been necessary to permit the passage of the matrices along the bar under the infiuence of the carrier devices untily they arrive at the usual point of release; and this'operation was frequently attended by muchvloss of time. In order to overcome this difficulty and permit the in-v stantaneous removal of the matrices I now mount the distributer bar and screws so that they may be separated laterally in order to disengage the matrices from the feed screws while they4 remain on the bar, so that they may be moved instantly along the bar and off fromv its end, or an individual matrix moved instantly along the bar until it reaehesthe point of release. I mount the bar so that i't`may be swung or moved laterally at the lower edge from its operative position and away from the feed screw or screws on one side, and I mount the screw or screws on the other side so that they may be separated from the bar.

The essence of the invention lies in mounting the bar so that it may be moved laterally from its operative position away from the carrying devices in order to permit the free removal of the matrices.

In the drawings I have shown my invention incorporated in a short distributer designed to separate the matrixes of different fonts according to font, but it is obvious that the same principle may be applied to the longer distributers, well known in the art, for delivering the matrices of a font or alphabet to the various channels of the magazines in which theyI are to be carried.

In the drawings: Figure 1 is a side elevation of my distributing mechanism with portions broken away to show the internal construction. Fig. 2 is a vertical cross-section on the line 2 2, with one of the feed screws and the distributer bar moved from their normal positions to permit the speedy removal of the matrices. Fig. 3 is a section on the same line as Fig. 2 with the parts in their voperative positions. Fig. 4 is a side view of the distributer bar and its support, one end being broken away to show the supporting pivo -Referring to the drawings, A represents a portion of the stationary framework, which may be of any suitable form and construction.

B is the horizontal distributer bar, having lts lower edge of V form 1n cross-section,

and with longitudinal teeth thereon for the purpose of suspending the individual matrices, C, as they are advanced along the bar, and releasing them at the proper points. These teeth maybe varied in form and ar' rangement at will, provided only that they are adapted to engage the correspoiuling teeth of the matrices in a` manner well understood by those familiar with the art.

The matrices are of a form well known in connection with Mergenthaler machines, each having in its upper edge a V shaped notch with teeth in the two edges, these teeth being varied in number or arrangement according to the characters borne by the respective matrices. p

D, D are two horizontal screws lying parallel with the distributor bar in position to engage the upper and lower edges of the passing matrices on one edge. D2 is a third screw-arranged to lengage the opposite edge of the matrices. These screws correspond f the exis of the ster-ew D" vte these commonly need in /.ergent machines, and serve only to aree die inetrices one after another along the dis vridnier har until they arrive at the peints er' release, when the matrices fall clear er the screws and the her by gre viy.

Se far as described the parte may he ,ef ordinary eenserueien end znedeef opere tien. instead, however, ef Securing ':he dietriinder loer rigidly in piace, :is heretofore, I new rneuniI its ends en herizentei pivots, Z1, seeded in the mein-frame, er other snpport, the arrzmgenient being auch het when desired. he iewer epereive edge of the har may be evvnng ietereily around the pivote, carrying with it the nmrieee .suspended thereon, se hat their eers will he disengaged from -the screws D and D, ns shown in Fig. 2.
